Atlantic No. 5274
Printable tracking charts (great circle).
Custom NAO form
A custom NAO form courtesy of Rick Rohrer.
Form 108 = NAO + 104
New form 108. We have combined our NAO form and the Form 104 to make what we call a Form 108. This is for those who choose do to sight reduction with the NAO sight reduction tables.
Form for solar index correction
This form is used to carry out index correction measurements using the upper and lower limb of the sun. They are designed to guide users to a comparison with the correct value of the sun's Semi-diameter as a test of the measurements. This is the optimum method to use to prepare for lunar distance measurements.
Navigation star chart
This is a hi-res pdf of a star chart specifically marking the 57 navigation stars. Could be helpful in learning the stars.
New form 104
We have added a newly designed form for sight reduction. This is our basic form 104 for reducing all sights using 249 or 229, but it has been redesigned by Frank Oliver to flow straight down the page. Our present form is more tabular than linear. Thanks Frank. We are sure others will like your new idea.
Pacific No. 5270
Printable tracking charts (great circle).
Precomputing forms
A convenient form for precomputing cel nav sights designed and shared by Gary Rose. If you have comments or suggestions, please post a note in the Cel Nav General Discussion group.
Starpath workforms
These forms are used for sight reduction of all bodies using Pub. 249, 229 or the Nautical Almanac Office version of sight reduction tables that appear in all nautical almanacs since 1989. There is also a form for LAN sights.
Universal Plotting Sheets
Use these sheets for plotting celestial LOPs or for any application that calls for a small section of a Mercator chart. The pdf file for these has two formats. They are both letter size, but could be printed any size. Everything would scale properly. We use these for the celestial course and for the weather course.
Coastal Nav
50-90 Rule for Tidal Currents
This form was developed by the USPS to be used with our 50-90 Rule for predicting tidal currents between peak and slack. A copy of the form is available at:

Form for 50-90 Rule

We appreciate this valuable contribution from the Power Squadrons.

Log and Knotmeter Calibration
This is a convenient form for calibrating log and knotmeter (generally done simultaneously) along with instructions for its use. The value of this form and procedure is it allows you to make the calibration even in the presence of wind or current.
Portable compass rose
This graphic is designed to be printed on a clear mailing label, which can then be cut out and pasted onto a chart. It is a replica of a compass rose than you can paste onto any part of a chart that might need one. It is especially valuable for kayakers or other small craft operators that much rely on folded charts.
Logbook pages
Every navigator has a favorite logbook format. This is the simple one we use. Designed for two facing pages, on letter size paper.
Parallel Indexing sheet
This is just a series of straight lines on a letter size paper intended to be printed on to a clear plastic overhead transparency sheet. They are used to plan and evaluate various parallel indexing maneuvers on the radar screen.
Portable range scale
This graphic is discussed in the Radar Trainer program. It is much like the old loran interpolation scales. You can cut them to match the range-ring spacing on your radar screen and paste onto a card or -- as we use them -- a tongue depressor, for quick distance measurements on the radar screen. Also useful with the Radar Trainer simulator.
Radar plotting sheets
These plotting sheets are designed for solving relative motion problems. Sometimes called transfer plotting sheets or maneuvering boards. They are designed for printing on letter paper.
Starpath VHF Channel Guide
A small card that conveniently reminds of channel usage and phonetic alphabet. Left click to view, right click to download. Prints from a pdf file, native size is 4.25" x 5.5". Ideal for posting near the radio for new radio users. Part of the Starpath post card series.
